Joint report of the Second International Workshop on Lymphocyte Alloantigens of the Horse, held 3-8 October 1982

Abstract

The Second International Workshop on Lymphocyte Alloantigens of the Horse was held 3-8 October 1982. At this workshop, the 6 specificities identified at the first workshop were confirmed and an additional 5 new specificities were identified and given workshop nomenclature. Four of the new specificities, products of the ELA locus, were named ELA-W7, W8, W9, and W10. An additional specificity, designated ELY-2.1, is the product of a locus independent of the ELA locus. Cell isolation methods were compared at this workshop. Technical variation in methods clearly affected reactivity of many reagents. However, when highly selected reagents were used, antigen assignment did not differ regardless of the cell isolation method. Based on the comparison of methods, isolation procedures in which thrombin was used were more effective than those relying on carbonyl iron or slow centrifugation.
